Annual Recurring Revenue (ARR) is a business metric that measures the predictable yearly revenue generated from subscription-based products or services with contracts lasting at least 12 months.

ARR is commonly used by SaaS and subscription-based businesses to track recurring revenue growth, customer retention, and long-term business performance.

Unlike one-time sales revenue, ARR only includes recurring subscription income and excludes variable or non-recurring charges.

How Is ARR Calculated?

ARR is calculated by adding the total annualized subscription revenue and adjusting for expansion revenue and customer churn.

ARR= Annualized Subscription Revenue + Expansion Revenue − Churned Revenue

ARR calculations generally exclude:

• One-time setup fees
• Variable service charges
• Non-recurring payments

This helps businesses focus only on predictable recurring revenue streams.

Why Is ARR Important?

Annual Recurring Revenue helps businesses:

• Forecast long-term revenue growth
• Measure subscription business performance
• Track customer retention
• Evaluate recurring revenue trends
• Support financial planning and investor reporting

ARR is one of the most important metrics for SaaS companies because it provides visibility into stable and predictable future revenue.

ARR and Business Growth

Businesses often analyze ARR in different ways to better understand performance and growth opportunities.

For example, companies may compare:

• ARR from new customers
• ARR from existing customers
• Expansion revenue from upselling
• Revenue lost from customer churn

This analysis helps businesses identify which areas contribute most to recurring revenue growth.

ARR vs MRR

Annual Recurring Revenue (ARR) and Monthly Recurring Revenue (MRR) are closely related metrics.

ARR

Measures recurring revenue generated annually.

MRR

Measures recurring revenue generated monthly.

Businesses commonly use MRR for short-term tracking and ARR for long-term financial forecasting and growth analysis.
